Subject: bug#9591: 24.0.50; buffer name completion
Date: Sat, 24 Sep 2011 08:28:13 -0400

If I type C-x k mes TAB, it completes to ` *message-viewer RMAIL'.
Killing that buffer was rather a screw.

I just fixed rmail so that won't be a screw.  But I think this
completion is a bug in its own right, and should be fixed too.

I think it is a bug to complete to a buffer name that starts with a
space, when the user did not type an initial space in the buffer name.
These buffers are not supposed to be visible unless the user
specifically asks to see them.
